Sherry had a scan on an ankle injury picked up in the 17-6 loss at home to Cardiff Blues at the weekend and a spokesperson said that they were hopeful he would be fit.
The hooker crisis has eased somewhat with Damien Varley, who has been sharing the position for most of the season until Sherry got an edge in recent weeks, available again.
Varley missed the loss to Cardiff Blues through illness, but he has made a full recovery and will be available for the trip.
Scrum-half Conor Murray will be available after being forced off in the opening quarter with a cut lip.
And tighthead prop Stephen Archer, another early casualty against the Blues, has recovered from a dead leg and will also be in the mix for the crucial clash.
Luke O'Dea, who missed the Cardiff game through illness, has fully recovered and will train today, but Johne Murphy is troubled by a hamstring injury and could miss this weekend's action, which also includes a British & Irish Cup match against Plymouth.
Munster train today in University of Limerick when it is expected that Rob Penney and his management team will make a call on Sherry's fitness.
Meanwhile, Paul O'Connell will this afternoon outline details of the back injury that threatened his career. He will front a press conference in Limerick where he will chart his recovery plan and hopes for an April return.
